EGG- BEATER.

Application filed May 21,

This invention relates to egg beaters or mixers for general use of the manually perable type commonly used around the household. Beaters of this type usually employ one or more sets of agitator blades mounted in a metal frame rotated by operating a handle upon a shaft to which is secured a master gear which in turn rotates the agitators. I, Another handle is usually employed to form-a holding means for the complete 1 device. These heaters areusually constructed out of light but stiff strip iron or wire or other sultable cheap material which is durable and 111- expensive to work.

This invention relates more specifically to the type of beater usually found as a household utensil and employstwo rotatable beaters and has for its purpose to construct a heater that is light, inexpensive and more efficient than those heretofore manufactured. In order to accomplish this result the beater is formed principally of wire and .conslsts essentially of two rotatable heaters, one rotating entirely within the other and one rotating in a reversed direction relatively to thev other.

Other objects and advantages willbe apparent from the following description of one embodiment of the invention, and the novel features will be particularly defined in the appended claims;

The embodimentof the invention as illustrated in the drawings consists of the usual handle 1 attached to the upper frame-member 3'which forms a support for the operating shaft 5 and carries the lower frame members taken along line 5+5 of 1926. Serial no 110,651.

7, 9'. The upper or, main frame member 3 is constructed from strip iron and formed into a U-shape formationhaving a bottomfportion 11 and two side arms or supports 13, 15. The two ends17, 19 are brought together and fastened to the handle 1 by rivet 21.

The entire operating mechanism is mounted withinthe' upper frame 3. For this pur pose the side members 13, 15 are drilled or punched at approximately their centersto provide bearings for the horizontal shaft 5, and to which is clamped'the two driving sprockets 23, 25 in the manner shown more" particularly in Figs. 2 and 6. Shaft 5 may be supplied with the usual handle 6 'if desired. The teeth of the sprockets 23, 25 may conveniently comprise radially arranged el liptical apertures around the peripheral portion of the sprockets and into whichthe teeth of cooperating pinions may protrude. Such a sprocketmayeasily be stamped in one operationfrom sheet material. Sprockets 23,25

are held-to the shaft inspaced parallel rela 7 tionship by the spacer members 27,29; These spacer members are formed with integral extending riveting lugs and are curved at their center portions tofit the shaft 5 snugly when 1 their surfaces are. brought together. The two spacers are riveted to the sprockets with their faces together, after which shaft 5 is spacers and keyed theretoby means of. a pin. Shaft 5 and thetwo sprockets are thereby securely mounted for rotation withinframe 3. Secured to and depending fromthe upper frame 3 are the lower frame members 7, -9 which consist oftwo wire members; eachbelng of a U formation having their upper extremities fastened to the side arms ofthe upgerframe as illustrated more particularly in ig. 2. These lower framemembers extend through slots inthe bottom portion 11 of the upper frame 3 close to the inner faces of the arms 13, 15. The extreme ends of the wire lower frame members 7 and 9' are bent sharply at right angles and inserted outwardin position holdsthes ewire members rigidly against the fiat surface of the side members 3.5 inserted between the curved portion of the J as clearly illustrated. This brace is held from vertical movement by having integral lugs formed on its four corners and mserting these lugs through apertures in the side arms of the upperframe nember. The two lower frame members being thus secured to the upper frame member are extended down wardly in U formation and clamped together at their lower, curved ends by clamping ele members securely in spaced relationship. The two lower frame members are in this manner clamped closer together atthe lower extremity than at the upper extremity which of necessity causes; these members to be curved inwardly atthe'bottom, thereby placingta tension uponthe lower frame members whichadds totheir rigidity and firmness;

Within the lower frame are mounted the two heaters 35, 37, one entirely 'within the other, each composed of two bent wires'with. their four upper ends'brought together at the top and their two lower curved ends securely held by clamps 39, ll'similar to clamp 33.

The four wires of the outer beater are broughttogether atthe upper end and inserted through the center hole in the bottom portion 11 of vthe upper frame and through four apertures' in a thrust disc 47 and thence through thehub of a pinion a5 and peened thereto, which pinion mesheswith sprocket 25' to be rotated thereby. The two pairs of wires constitutingthe inner beater are held togethertheir lower ends by clamp ll similar to clamp 33 and curved upwardly in a similar manner toithe; other beater blades, ex,- tended'through the aperturein'thecenter of the bottom portion 11 "of the upper frame member, then througha single aperture in the thrust disc l7 which acts as a steady bearing, and then through a clamping sleeve 48 placed within the hub of the'pinioii l5and thence'through andsecured 'to' pinion l9;

Pinion i9 is mounted t'ofm'esh'with a sprocket 23. and-- adapted to be rotated thereby and rests upon the upper face offpinion 45 which forms a thrust bearin therefor. I r

a The lower endsof the lower frame and the two boaters are secured together-by means of a pin 51 which is inserted through the threeclamps 38-, 39and 41, and upset at each end to prevent any vertical movement of the heaters relatively to the lower frame'membe r. rigidly against pin 51, whereas clamps 39 and 41 are made with, a loose fit around said pin so as to allow rotationof these clamps relatively to the pin which is held stationary by clamp 33; I

is to be noted that sprocket 25 meshes with 9111101145 upon one side of the axis of 'the'pi'mons, whereas sprocket 23 meshes w1th The clamp 33 is curved tightly and pinion 49 upon the other side of the axis of I the pinions, thereby causing the two beaters tobe rotated in relatively oppositedirections uponrotation of'shaft 5. Also thetwo sprockets 23, 25 are constructed with difier ent diameters to cause the beater to be rotated at different speeds of rotation as well as different directions of rotation.

From the above description of this device its operation is obviously clear and simple and is as follows: The operator grasps the device by handle 1 and rotates shaft 5 by, means of handle 6, thereby turning sprockets 23, 25, which cooperatevith pinions 45, 49 to cause the two beaters 35 and 3710 be rotated in relatively reversed directions and at different speeds of rotation. From the foregoing it is clear that a very efficient, c'o'm pact and rapid beater is constructed adapted to be manufactured with a minimum amount of skilled labor and at duction'.

It isobvious that'minor changes maybe made without departing from the spirit of the invention, for example, the pinions may a'very low costof probe stamped from flat material and supported zontallyin said upper frame;
